Title: Mechanism for supplying cut paper
Inventor: NAKATANI SHIGEHIRO
IPC: B65H3/06
Filed: 1990-02-23
Abstract: PURPOSE:To surely supply sheets of cut paper one by one by supplying sheets of cut paper to be supplied while forwardly wrinkling each sheet between two pickup rollers. CONSTITUTION:As to two pickup rollers 2, 3 both of which make contact with the upper surface of a sheet of cut paper 1, the peripheral velocity v2 of the pickup roller 2 which is the front of the two in the direction of paper supply is lower than that v3 of the pickup roller 3 which is the rear in the direction of paper supply. Therefore the amount of sheets of cut paper supplied by the rear pickup roller 3 is larger than that by the front pickup roller 2. As a result, the length of the cut paper 1 between both pickup rollers 2, 3 is longer than the space between both pickup rollers 2, 3 and only the uppermost sheet of cut paper 1 is curved upward and floats up between both pickup rollers 2, 3 in the same way as when the sheet is partially wrinkled by two fingertips, and the sheet is separated from lower sheets of cut paper and supplied.

IPC: F02F11/00
Filed: 1994-02-18
Abstract: PURPOSE: To prevent separation and a slide of a facing material and a core under a high load condition. CONSTITUTION: A gasket 20 has two outer facing material layers 28 positioned in mutually opposing side parts 30, 32 of a central metal shim 26. A perforated core 34 is arranged between the facing material layers and the shim. A width of the shim can be changed so as to control the whole width of the gasket 20. The core 34 is fixed to the shim 26 by using a thermosetting adhesive 36, extends in the facing material layers, and has a tongue-shaped piece 48 for clinching the core and the facing material layers together. The use of the perforated core prevents blistering of the facing material layers during gasket manufacturing. The two perforated metal cores mutually separated by an adjustable width shim provide manufacturing advantages, minimize a facing material layer thickness, and can increase strength.
